KRUGER NATIONAL PARK

The park lies in the northeast of South Africa, in the eastern parts of Limpopo and Mpumalanga provinces. Phalaborwa, Limpopo is the only town in South Africa that borders the Kruger National Park. It is one of the largest national parks in the world, with an area of 19,485 km2 (7,523 sq mi). The park is approximately 360 km (220 mi) long, and has an average width of 65 km (40 mi). At its widest point, the park is 90 km (56 mi) wide from east to west.To the north and south of the park two rivers, the Limpopo River and the Crocodile respectively, act as their natural boundaries. To the east, the Lebombo Mountains separate it from Mozambique. Its western boundary runs parallel with this range, roughly 65 km (40 mi) distant. The park varies in altitude between 200 m (660 ft) in the east and 840 m (2,760 ft) in the south-west near Berg-en-Dal. The highest point in the park is here, a hill called Khandzalive. Several rivers run through the park from west to east, including the Sabie, Olifants, Crocodile, Letaba, Luvuvhu and Limpopo Rivers.

Climate

​

The climate of the Kruger National Park and lowveld is subtropical/tropical, specifically a hot semi-arid climate (Köppen BSh). Summer days are humid and hot. The rainy season is from September until May. The Kruger National Park website lists September and October as the driest periods, culminating at the beginning of the rainy season late in October. Because the park spans 360 kilometres or 220 miles from north to south, climate can vary throughout the park. Skukuza in the southern part of the park is about 2 to 3 °C (3.6 to 5.4 °F) cooler throughout the year than Pafuri in the north, with significantly more rainfall.

Vegetation

Plant life consists of four main areas, which correspond roughly to the four quadrants of the park. The main veld types are determined by the rainfall gradient (400 to 750 mm per annum) and geological substrates.

Shrub mopane veld

Shrub mopane covers almost the entire northeastern part of the park.

Red bush-willow and mopane veld

This area lies in the park's western half, north of the Olifants River. The two most prominent species here are the red bush-willow (Combretum apiculatum) and the mopane tree (Colophospermum mopane).

Thorn trees and red bush-willow veld

This area lies between the western boundary and roughly the centre of the park south of the Olifants River. Combretums, such as the red bush-willow (Combretum apiculatum), and Acacia species predominate while there are a great number of marula trees (Sclerocarya caffra). The Acacias are dominant along the rivers and streams, the very dense Nwatimhiri bush along the Sabie River between Skukuza and Lower Sabie being a very good example.

Knob-thorn and marula veld

South of the Olifants River in the park's eastern half, this area provides the most important grazing land. Species such as red grass (Themeda triandra) and buffalo grass (Panicum maximum) predominate while the knob-thorn (Acacia nigrescens), leadwood (Combretum imberbe) and marula (Sclerocarya caffra) are the main tree species.

Local vegetation communities

Several smaller areas in the park carry distinctive vegetation. The Pretoriuskop sourveld and Malelane mountain bushveld receive relatively high rainfall. Here sickle bush and silver cluster-leaf (Terminalia sericea) are prominent. The sandveld communities northeast of Punda Maria are equally distinctive, with a wide variety of unique plant species. The bush-clad hills along the Levuvhu River also shelter an interesting floral diversity and some near-endemic species.

All the big five game animals are found at Kruger National Park, which has more species of large mammals than any other African game reserve (at 147 species). There are webcams set up to observe the wildlife.

Kruger supports packs of the endangered African wild dog, of which there are thought to be only about 400 in the whole of South Africa.

Birds

 

Harlequin quails (C. delegorguei) are irruptive migrants and late summer breeders in the grassy plains. They are plentiful nomads after good rains, but almost absent during dry years.

Yellow-billed oxpeckers (B. africanus) are obligatory symbionts of large mammal herbivores. After an absence of over 80 years, they made an unaided comeback starting in 1979.

A fairly uniform aggregate of bird species is present from the southern to central areas of the park, but a decline in diversity is noticeable in the mopane-dominated flats northwards of the Olifants. Most species breed in summer when rains sustain most vegetable and animal food, but the larger birds of prey conversely breed during the dry winter, when their prey is most exposed. Out of the 507 species of birds found at Kruger, 253 are residents, 117 non-breeding migrants, and 147 are nomads.

Constituting the southern lowveld, the park's avifaunal affinities are mainly with the tropical north. Some representatives of this group are the African openbill, hooded vulture, Dickinson's kestrel, white-crowned lapwing, brown-necked parrot, Senegal coucal, broad-billed roller, trumpeter hornbill, Böhm's spinetail, tropical boubou, Meves's starling and scarlet-chested sunbird. Some 30 waterbird and wader species are dependent on the rivers or associated dams, including the African finfoot, white-backed night heron, white-crowned lapwing and water thick-knee. Other species are limited to riparian thicket or forest, including African goshawk, crested guineafowl, Natal spurfowl, Narina trogon, Pel's fishing owl, bearded scrub robin, terrestrial brownbul and black-throated wattle-eye. This habitat is often reduced by drought or floods or the understorey is opened up by elephant.

Some of the larger birds require large territories or are sensitive to habitat degradation. Six of these birds, which are by and large restricted to Kruger and other extensive conservation areas, have been assigned to a fanciful grouping called the "Big Six Birds". They are the lappet-faced vulture, martial eagle, saddle-billed stork, kori bustard, ground hornbill and the reclusive Pel's fishing owl, which is localized and seldom seen. The 2011 aerial survey found 22 martial eagle nest sites, the 2015 survey an additional 17, while the 2020 survey found 70 nest locations in all, though the activity of these has yet to be determined. There are 25 to 30 breeding pairs of saddle-billed storks in the park, besides a handful of non-breeding individuals. In 2012 178 family groups of ground hornbills roamed the park and 78 nests were known, of which 50% were active. A 2013 study estimated that 904 pairs of white-backed vulture, 78 pairs of lappet-faced vulture and 60 pairs of white-headed vulture breed in the park.

Other vertebrates

Kruger is inhabited by 114 species of reptile, including black mambas, African rock pythons, and 3,000 Nile crocodiles. As yet, knowledge of the densities and distributions of the reptiles, especially on smaller spatial scales, is limited by sampling bias and a strong dependence on the park's public infrastructure is evident. 34 species of amphibians are found in the park, as well as 49 fish species. A Zambezi shark, Carcharhinus leucas, also known as the bull shark, was caught at the confluence of the Limpopo and Luvuvhu Rivers in July 1950. Zambezi sharks tolerate fresh water and can travel far up rivers like the Limpopo.

Invertebrates

 

A seasonally fluctuating biomass of arthropods is observed in response to the summer rainfall regime and the mostly deciduous vegetation, as shown by sampling during 11 months in grassland near Satara Camp.

219 species of butterfly and skipper are native to the park.The fastest and most robust of these belong to the genus Charaxes, of which 12 species have been recorded. Genera Papilio and Acraea are also well-represented, with about 10 and 15 species respectively The total number of Lepidoptera species in the park is unknown but could be in the order of 7,000, many of which range widely in African savanna. The mopane moth in the northern half of the park is one of the best known, and communities outside the park have at times been given permits to harvest their caterpillars. The park has a high diversity of termites and 22 genera are known to occur, including the mound-building genera Macrotermes, Cubitermes, Amitermes, Odontotermes and Trinervitermes. A new species of woodlouse, Ctenorillo meyeri, has been discovered inside termite nests, east of Phalaborwa and near Mopani Rest Camp. It is the first instance of a termitophilous species from the family Armadillidae. Many species of mosquito occur in the park, including the Culex, Aedes and Anopheles genera which target mammals. A. arabiensis is the most prevalent of the 9 or more Anopheles species in the park, and their females transmit malaria. As of 2018, 350 species of arachnids, excluding ticks and mites, are known from Kruger. These are mostly true spiders, including 7 species of baboon spider, but also 9 scorpion and 7 pseudoscorpion species, 18 solifugid species (sun and roman spiders), 2 species of harvestmen and 1 species of tailless whip scorpion.
